摘要
东流水道位于长江下游。近年来,该水道航道条件出现了较大的不利变化趋势。以河道观测资料为基础,分析东流水道左岸边滩演变特征及该边滩河床演变对本河段航道条件的影响,指出东流水道航道整治工程实施后,左岸边滩出现的新的演变是造成本河段近年来航道条件趋坏的重要原因。在此基础上,对左岸边滩演变和本水道航道条件变化趋势进行预测,认为主航道所在的西港航道条件仍有进一步衰退的可能,为本水道后期航道治理思路和工程设计提供参考。
Dongliu waterway is located in the lower Yangtze River.In recent years,its waterway condition is getting increasingly bad.Based on the observed data,this paper analyzes evolution characters of the left beach of Dongliu waterway and the effect of the left beach’s evolution on the waterway condition.It points out that the new evolution characteristic of the left beach after implementation of the waterway regulation project is an important reason for the increasingly badding of the waterway condition.It also predicts the trend of the bed evolution of the left beach and the waterway condition,and points out that the main channel called Xigang may be still in a shrinking trend.These researches may serve as reference for the channel regulation ideas and engineering design in the follow-up project.
